Frequently Asked Questions
What happens with multiple sheets?
The first (active) sheet is converted to CSV. Each sheet must be converted separately.
Are formulas included in the output?
CSV contains only the calculated values, not the formulas themselves.
How are dates and numbers handled?
Dates and numbers are exported in their displayed format. Special formatting like currency symbols is preserved as text.
Is this tool really free?
Yes, completely free with no hidden fees, no watermarks, and no sign-up required. You can convert as many files as you need.
Are my files private and secure?
Absolutely. Every conversion runs in an isolated, in-memory process. Your files never touch the disk, are never stored or shared, and are deleted from memory the moment your download is ready.
